Answer:
88
Step-by-step explanation:
![\frac{86 + 94 + 88 + 95 + 89 + x}{6} = 90](https://tex.z-dn.net/?f=%20%5Cfrac%7B86%20%2B%2094%20%2B%2088%20%2B%2095%20%2B%2089%20%2B%20x%7D%7B6%7D%20%20%3D%2090)
The mean would be the sum of all the math quiz grades divided by the number of quizzes taken.
Solve for x:
![86 + 94 + 88 + 95 + 89 + x = 540](https://tex.z-dn.net/?f=86%20%2B%2094%20%2B%2088%20%2B%2095%20%2B%2089%20%2B%20x%20%3D%20540)
![452 + x = 540](https://tex.z-dn.net/?f=452%20%2B%20x%20%3D%20540)
![x = 88](https://tex.z-dn.net/?f=x%20%3D%2088)
Thus, Allen needs at least an 88 to obtain a mean of at least 90.
Answer:
The correct ans is....

So the first thing you would have to is to find a common denominator so a common denominator between 11 and 15 is 165. 3/11 * 15 =45/165 next you would do 7/15 * 11=77/165 no that both denominators are the same we add the numerator but the denominator stays the same so 45/165 + 77/165 = 122/165
and since it can't be reduced any more 122/165 is your answer.
hope this helps :)
